NEW YORK -- I hear Osama bin Laden laughing. I heard him all day on Sunday and Monday as the mass murder of Sept. 11, 2001, was memorialized at the Pentagon and in that field in Pennsylvania and especially here, where the most people died and where countless cameras recorded it all for posterity and an abiding, everlasting anger. He laughs, the madman does, whenever George Bush says, as he has over and over, that America is "winning this war on terror." Bin Laden knows better. He has already won.
